I am seeding a database using distributed availability group. Seeding is automatic but synchronization mode is asynchronous. Log stream compression for automatic seeding is NOT enabled via TF 9567. Value for 'is_compression_enabled' in DMV 'sys.dm_hadr_physical_seeding_stats' is showing 0 during seeding operation.
As per MS documentation 'Log stream compression is enabled by default for asynchronous replicas.' According to this, shouldn't log stream compression be enabled by default for this seeding operation? That's why I got this question if this is same behavior for Distributed availability groups also.
